EP Telecom v Acumuladores Moura: Battery Carrier Patent Appeal Decided
EP Telecom Serviços Ltda and two individual co-plaintiffs brought a declaratory judgement action against battery manufacturer Acumuladores Moura S/A over BRPI2015573A2, covering a modular shielded carrier for external battery protection. The Court of Justice of São Paulo upheld the defendant’s appeal in full while dismissing the plaintiffs’ cross-appeal as prejudiced.
São Paulo appellate court rules for Acumuladores Moura in battery carrier dispute
This case, filed under case number 1050314-26.2020.8.26.0100 before the Court of Justice of São Paulo, arose as a declaratory judgement action brought by EP Telecom Serviços Ltda together with individual co-plaintiffs Enio Carlos Prudente and André Luiz Lima Amorim against battery manufacturer Acumuladores Moura S/A. The dispute centred on Brazilian patent application BRPI2015573A2, which covers a modular shielded set auto carrier designed for the external protection of batteries in parking environments — a structural accessory relevant to the automotive battery sector.
The case reached the appellate division of the Court of Justice of São Paulo, where both parties had filed appeals. On 23 September 2025 the court issued its decision: the defendant Acumuladores Moura’s appeal was upheld in its entirety, while the plaintiffs’ appeal was declared prejudiced — a procedural outcome meaning it was rendered moot by the success of the opposing party’s appeal and therefore not assessed on its merits. The practical effect is that the lower court’s ruling was reversed in the defendant’s favour.
The duration of the proceedings from filing to closure is not fully recorded in the available public data, though the matter closed in late September 2025. The dismissal of the plaintiffs’ appeal as ‘prejudiced’ is consistent with Brazilian civil procedure practice where a successful cross-appeal extinguishes the need to examine the losing party’s grounds. What remains unknown from the public record includes any damages sought, the specific declaratory relief requested, and whether the underlying patent application has been granted or is still pending.

São Paulo appeal upheld for defendant: what the ruling means for both parties
Defendant’s appeal upheld — lower decision reversed in Moura’s favour
When an appellate court upholds a party’s appeal, it finds the lower court erred in that party’s disfavour and corrects the outcome accordingly. Here the Court of Justice of São Paulo found sufficient grounds in Acumuladores Moura’s appeal to rule in its favour. The plaintiffs’ cross-appeal was simultaneously declared ‘prejudiced’ — a standard Brazilian procedural outcome signalling it became moot once the defendant’s appeal succeeded and required no separate adjudication.
Appellate reversalDeclaratory relief sought by plaintiffs denied at appellate level
EP Telecom and the individual co-plaintiffs pursued declaratory judgement, suggesting they sought formal judicial recognition of rights connected to BRPI2015573A2. The appellate outcome — upholding Moura’s appeal and rendering the plaintiffs’ appeal moot — indicates the declaratory relief was not granted. This weakens the plaintiffs’ enforcement posture and may affect their ability to assert the patent application commercially until a further legal avenue is pursued.
Declaratory relief deniedAcumuladores Moura secures appellate victory against patent assertion
Acumuladores Moura’s successful appeal is commercially significant: it removes an adverse lower court finding and suggests the court found the plaintiffs’ declaratory claims legally or factually insufficient. For Moura, the ruling provides short-term protection against this specific assertion of BRPI2015573A2. However, the underlying patent application’s status and the possibility of further proceedings — including any appeal to superior courts — remain relevant considerations.
Defendant prevails on appealBattery carrier IP rights remain contested in Brazil’s automotive sector
This outcome is consistent with the broader complexity of asserting patent application rights in Brazil before formal grant. Competitors and battery manufacturers operating in the Brazilian automotive accessories space should monitor BRPI2015573A2’s prosecution status. An appellate ruling in the defendant’s favour at this stage does not necessarily extinguish the applicants’ IP rights permanently — patent grant could reopen enforcement options, raising ongoing FTO concerns for the sector.

Official order — verbatim text
The verdict phrase — ‘upheld to the defendants’ appeal, prejudiced to the plaintiff’s appeal’ — reflects standard Brazilian appellate practice. ‘Upheld’ confirms the appellate panel found merit in Acumuladores Moura’s grounds, reversing the lower court in its favour. ‘Prejudiced’ is a procedural declaration, not a substantive finding against the plaintiffs: it signals the court deemed the plaintiffs’ appeal rendered moot by the success of the opposing appeal, requiring no separate analysis of its merits. This outcome is commercially equivalent to a defendant win at appellate level.
BRPI2015573A2 — Modular Shielded Battery Carrier for External Protection
BRPI2015573A2 is a Brazilian patent application covering a modular shielded set auto carrier designed for the external protection of batteries in parking contexts. The invention addresses physical shielding and modular assembly of battery carrier structures, targeting the automotive battery accessories segment. As an application (indicated by the ‘A2’ publication code), it represents a pending right at INPI — the Brazilian National Institute of Industrial Property — and has not necessarily been examined to grant, which is materially relevant to its enforceability in litigation.
Strategically, this application sits at the intersection of automotive accessories and battery protection hardware — a space growing in commercial significance as Brazil’s vehicle fleet expands and battery maintenance infrastructure develops. For competitors of the named plaintiffs and manufacturers such as Acumuladores Moura, the application represents a potential IP constraint on modular battery carrier designs. The litigation outcome suggests courts will scrutinise the enforceability of such applications carefully, but grant by INPI would substantially alter the risk profile for the entire sector.
Should you run an FTO analysis against BRPI2015573A2?
Any company manufacturing, importing, or distributing modular battery carrier systems or external battery protection accessories in Brazil should assess their exposure to BRPI2015573A2. Although this case ended in the defendant’s favour at appellate level, the underlying application may still proceed to grant at INPI. A granted patent would create enforceable rights that could be asserted against battery carriers, housing accessories, and related modular protection systems — directly relevant to automotive OEMs, aftermarket suppliers, and battery manufacturers operating in Brazil.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map their product architectures against BRPI2015573A2’s claims in real time, identify design-around opportunities, and set automated prosecution alerts for INPI status changes.

What this case signals for Brazil’s automotive battery IP landscape
The outcome highlights enforcement risks when asserting patent applications before grant in Brazilian courts.
Pre-grant patent assertions in Brazil carry significant procedural risk
Asserting rights tied to a patent application rather than a granted patent creates vulnerability at every appellate stage. Brazilian courts have discretion to dismiss declaratory claims where the underlying IP right is not yet fully established. Practitioners advising clients on Brazilian patent strategy should weigh enforcement timing carefully against prosecution progress.
Battery manufacturers face recurring modular carrier IP disputes in Brazil
BRPI2015573A2 covers a niche but commercially relevant product — shielded modular carriers for battery external protection. As Brazil’s automotive aftermarket grows, expect continued IP friction around battery housing, protection accessories, and carrier systems. Proactive FTO analysis against pending Brazilian applications is increasingly material for manufacturers like Moura.
AMORIM v ACUMULADORES — key questions answered
The Court of Justice of São Paulo upheld Acumuladores Moura’s appeal in full. The plaintiffs’ cross-appeal was declared prejudiced — meaning it was rendered moot by the defendant’s successful appeal — and was not assessed on its merits. The practical effect is a reversal of any adverse lower court finding against the defendant.
In Brazilian procedural law, an appeal is declared ‘prejudiced’ when a prior or concurrent decision renders it moot. Here, once the defendant’s appeal was fully upheld, the plaintiffs’ grounds no longer required adjudication. This is a procedural outcome — it does not constitute a substantive finding on the merits of the plaintiffs’ arguments.
BRPI2015573A2 covers a modular shielded set auto carrier for the external protection of batteries in parking environments — a structural accessory designed to protect automotive batteries externally. The dispute arose as a declaratory judgement action, suggesting the plaintiffs sought formal recognition of rights connected to this application against Acumuladores Moura, a major battery manufacturer.
BRPI2015573A2 carries an ‘A2’ publication code, indicating it is a published application rather than a granted patent. In Brazil, enforcement of patent rights typically requires grant by INPI. Asserting a pending application in litigation carries procedural and substantive risks, which may have contributed to the outcome in this case. The application’s current prosecution status at INPI remains a key variable for future enforcement prospects.
The ruling provides Acumuladores Moura with short-term protection against this specific assertion of BRPI2015573A2. More broadly, it signals that Brazilian appellate courts will scrutinise the enforceability of pre-grant patent applications. Battery manufacturers and automotive accessory suppliers in Brazil should monitor the application’s INPI prosecution status — a granted patent could materially alter the FTO landscape for modular battery carrier products.
